Augmented Reality (AR) applications can be used to improve tasks and mitigate errors during facilities operation maintenance. This article presents an AR system for facility management using a three-dimensional (3D) object tracking method. Through spatial mapping, the of interest, pipe trap underneath sink, is tracked mixed onto visualization. From that, maintenance steps are transformed into v...

The CubeSat Ambipolar Thruster (CAT) is nominally designed to operate on inert gas propellants with a target ΔV capability of greater than 1000 m/s. The design process for a prototype pressurized inert gas propellant feed system capable of storing enough propellant to meet this target and of delivering propellant at the flow rates of 5 15 sccm of xenon and pressures of 1 10 mbar required by CAT...

Prediction of pressure pulsation magnitude and their harmonic components for a multistage reciprocating compressor, piping and reservoir system depends on the input design and operating parameters. In the present paper, the results of the theoretical study carried out to study the effect of such parameters on pressure pulsations and their harmonics have been presented. The effect of pipe diamet...

batch culture of ralstonia eutropha using the recycled gas closed circuit culture system was conducted in order to develop a practical fermentation system for industrial autotrophic culture for poly (hydroxybutrate) production. the gas phase of the culture system consisted of substrate gas so that gases in this culture could be recycled as long as the amount of the gas consumed would be repleni...

Risk-Informed In-Service Inspection (RI-ISI) aims at prioritizing the components for inspection within the permissible risk level thereby avoiding unnecessary inspections. The two main factors that go into the prioritization of components are failure frequency and the consequence of the failure of these components. The study has been focused on piping component as presented in this paper. Failu...

In this work, an application of artificial intelligence in the oils & gas industry is developed to identify flow patterns horizontal and vertical pipes two-phase oil water, normalizing word information converting it numerical values through development neural network, whose input layer composed surface velocities each fluid, velocity mixture, volumetric fraction substances, diameter inclina...
